To: Banks

Peace, mercy, and blessings of God be upon you,

Subject: Launch of the Electronic Cheque Clearing System (ECCS).

Based on the powers vested in the Saudi Central Bank (SAMA) under its system issued by Royal Decree No. (M/36) dated 11/4/1442H, which includes the authority of the Central Bank to establish, develop, and operate the infrastructure for national payment systems, clearing, and settlement, and to issue rules, instructions, and guidelines, and to supervise and monitor payment systems, clearing, and settlement within its jurisdiction.

We inform you of the launch by the Saudi Central Bank of the Electronic Cheque Clearing System (ECCS), aimed at developing the cheque clearing process using digital image standards (cheque truncation); which helps in achieving several positives such as performing clearing on the same day, and reducing the costs of transporting paper cheques.

Accordingly, we attach the rules of operation of the Electronic Cheque Clearing System (ECCS), the guide, as well as a document with frequently asked questions about the system and its answers.

In case of any inquiries, you can contact us via email at: ECCS@SAMA.GOV.SA for review, awareness, and action.

And accept our regards,

Yazid bin Ahmed Al Sheikh Deputy Governor for Supervision

Distribution Scope:

• Banks and banks operating in the Kingdom.

1 Classification: 1 Introduction 1.1 Document Purpose The purpose of this document outlines in detail SAMA’s Rules & Regulations for eClearing System for Checks (ECCS). ECCS aims to improve the Check clearing process using digital image processing (Check truncation). ECCS truncates the exchange of Checks among participating banks and SAMA (as participating) using digital Check images instead of physical Checks. The process involves scanning and transmitting the electronic image of the Checks along with relevant data, rather than physically sending the Checks to SAMA (as clearing house), and delivering the issuing bank Checks digitally in the same manner. This conforms to international standards used in United States of America (Check21) and the rest of the world where Check truncation/automation is adopted. 1.2 Intended Audience EA, SAMA Enterprise Architecture Design team, party to ensure ECCS is designed, integrated, secured, and scaled to fit SAMA organization technical architecture direction, reviewing High Level Document (HLD) delivery DSD, SAMA Digital Solution Design team, party to ensure ECCS is designed, integrated, secured, and scaled to fit SAMA organization technical architecture direction, reviewing Lower-Level Document (LLD) delivery DCC, SAMA Digital Compute & Cloud (Server) team, party to finalize and prepare ECCS infrastructure and server architecture DEO, SAMA Digital Enterprise Operations team, party to review and approve SAMA Application-Infrastructure Design Network, SAMA Network, in charge of participating bank branches connectivity to ECCS application via SAMA network with adequate bandwidth allocated ESD, SAMA Enterprise System Development team, party that determine banks Check settlement and billing integration specification with Saudi Arabian Riyal Interbank Express (SARIE), Real-Time Gross Settlement (RTGS) system operated by SAMA via the SAP Core banking system.

6 Classification: 2 Scope 2.1 Scope/ Background These Rules & Regulations apply to all clearing items that are eligible for clearing through ECCS. Participants are required to adhere to the processes and conditions stated in these Rules & Regulations operational manuals. Although these Rules & Regulations make a functional distinction between the different Check clearing roles, one entity may play several roles in the clearing of Checks and other instruments through ECCS. For example, many Participants exercise a dual role as a Presenting Bank as well as an Issuing Bank at the same time. These Rules & Regulations shall be binding on all Participants of ECCS, including their agents, if any. 2.2 Business Objective 2.2.1 These Rules & Regulations outline the process and workflow for the operation of the ECCS and serve as a guide for participants of SAMA ECCS, to equip them with effective operating knowledge. 2.2.2 ECCS is intended to introduce a paperless Check clearing process, increase the efficiency of the clearing process and settlement process and to further achieve acommon day hold throughout the Kingdom. 2.2.3 ECCS enables the clearing of Checks through image and data (truncation) and the movement of physical Checks and other payment instruments between banksand between banks and theclearing housewill beeliminated. 2.2.4 These Rules & Regulations where applicable shall be read in conjunction with the following documents : 2.2.4.1 Negotiable instruments (Royal Decree No. 37 dated 11/10/1383) Bill ofExchange 2.2.4.2 Guidelines on Business ContinuityManagement for Participants ofSAMA ECCS ; and 2.2.4.3 Any othercirculars,standards,codes, notices, directivesissued bySAMA from time to time related to ECCS. 2.2.5 With effect from the Effective Date (determined and communicated) in accordance with the Rules & Regulations of ECCS, shall replace the existing physical check clearing arrangement. These Rules and Regulations supersede and nullify all previous check clearing rules, procedures, and arrangements. In the event of an emergency that necessitates operating under the manual clearing process, the previously applicable manual clearing rules and procedures shall be followed to the extent required. These Rules shall come into force immediately upon issuance of the official circular and approval. 2.2.6 Accordingly, SAMA and each ECCS Participant agree that with effect from the Effective Date, these Rules & Regulations shall commence to form a part of the governance framework of ECCS. 2.2.7 TheEffective Datereferred to in Clause.2.2.5 shall be: 2.2.7.1 A date determined by SAMA that is no earlier than ten (10) Business Days after all participants of ECCS submitted theirrespectiveapplication, duly completed in accordance with Clause 2.2.5 and Communicated by SAMA via written notice to all ECCS Participants prior to the Effective Date.

7 Classification: 2.3 The Business Proposed Solution 2.3.1 Implementation of eClearing System for Checks (ECCS) project is proposed to move current partially and manual clearing system to fully digitalized electronic clearing system of Checks.
